TAIING MACHINE.

Application filed April 13, 1922. Serial No. 552,204.

To all whom it may concern:

Be it known that I, PENnosn E. CHAP- MAN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented a certain new and useful Improvement in Taping Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a feed which shall be at once simple, and which will not interfere with handling the coil by the operator, to relieve the great muscular strain on the operator which is caused by the continually changing direction in pull as the tape is laid on the coil, and to increase the speed.

In the drawings Figure 1 shows a. convenient armature coil taping machine;

Fig. 2 is an edge view of the steady rest,

Fig. 3 is a view along line 33, Fig. 2.

2 is the frame, 3 is the shuttle or split wheel, which may assume many other forms or even be stationary, 4 is a roll of tape, 5 is a belt for driving said shuttle running over pulleys 6, 7 is a guide and tension brake over which the tape 4; is fed to the coil to be taped, 9 is my improvement, a steady rest; 11 is a chain cradle or hammock which runs on the pulleys 12, which I prefer to use as the working face of the steady rest 11.

I accomplish my object by the very simple method of attaching said steady rest 9 to the tape carrying portion or shuttle 3 of the taping machine, in such a manner that the stem y rest 9 takes up the pull of the tape. on the coil 10, instead of transmitting it to the operators hand.

To accomplish the feed I may make the steady rest 9 preferably of some thin section whose working face 11 is set at an angle to the axis of rotation such that as it rotates itwill have a tendency to feed the coil past the steady rest and thus through the machine, for it will then tend to act as if it were a threaded nut, for my preferred form is in fact a mutilated nut and might be a whole one, with a plurality of angular threads or corrugations.

This steady rest I prefer to make roughly of an L shape at the point where it comes in contact with the coil as shown, for thus I am able to provide a working face 11 and a guard or back 8 which prevents coil 10 jumping out of place and getting caught.

The term working face is used to designate that part of any steady rest which the object being worked on usually touches. The face or edge 11 or 11' of my steady rest is such a. working face. The guard or back 8 is also a working face. but is not so alluded to herein.

lVhile the steady rest 9 may have a rigid working face as described; for soft coils it is better to face it with a hammock 11 made of any flexible material but preferably made of smooth chain which runs over rollers or pulleys 12, for thus will the friction of the steady rest 9 against the coil be decreased and the strain of the coil against the steady rest will be more evenly distributed over the coil enabling the tape to be applied with a greater tension than otherwise.

I may dispense with the chain and use rollers only to face the steady rest instead of a combination as shown.

My invention is capable of other modifications, and use on other similar machine. I therefore use'the term taping machine to include any other devices of similar or allied nature.

Claim:

1. In a taping machine, the combination of a shuttle with a steady rest attached thereto.

2. In a taping machine, the combination of a shuttle with a steady rest attached thereto, having a working face placed to resist the pull of the tape.

3. In a taping machine, the combination of a shuttlev with a steady rest attached thereto whose working face is angula-rly directionated.

l. In a taping machine, the combination of a shuttle with an L shaped steady rest attached. thereto substantially as described.

5. In a. taping machine, the combination. of a. shuttle with an L shaped steady rest attached thereto whose working surface is angularly directionated substantially as described.

6. In a taping machine, the combination of a steady rest for receiving the pull of the tape on the coil and a movable working face.

7. In a taping machine, the combination of a shuttle, a steady rest attached thereto, and a movable Working face for said steady rest.

8. In a taping machine, the con'ibination of a. steady rest for receiving the pull of the tape on the coil With means for reducing the friction of the working face against the coil.

9. In a taping machine, the combination of a shuttle, a steady rest attached thereto having means for reducing the friction of the working face against the coil.

10. In a tat-ping machine, the combinationof a steady rest for receiving the pull of the tape on the coil and a movable Working face of flexible nia-tei'ial running over rollers.

In testimony whereof, I have hereunto affixed signature in the presence of two WltIICSSQS, this 10th day of April 1? PFNROSE E. CHAPIVMN. lVitnesses Miss-J. E. Kossen-m, E. F. 5112mm.
